Questions tagged [roblox]

Roblox is an online development platform targeted at kids and teens. It was created in 2006. Roblox uses Lua that has been modified by the Roblox team, known as Luau, to support Roblox games, which is fairly simple and easy to use.

Roblox is a free user-generated gaming site that makes players the architects of their own 3D worlds. Parts of the platform are a variety of objects, a scripting language and a website to host games. With a free account, one gets a character and a place, that can be customized. [ Source: developer.roblox.com ]

Roblox uses Lua, a lightweight programming language embedded into each game. It is easy to use and allows users to manipulate their games in any way possible. Roblox uses their own version of Lua 5.1, edited to work with the games, called Luau, which features type checking and various optimizations. An example would be the removal of tailcalls, making them not re-use the call stack, in favor of easier debugging. Luau allows users to do things such as creating their own GUIs, making structures such as sliding doors, adding animation to bricks, teleporting and killing players, etc.
